  1. 1. 3D virtual space for collaborative design reviews

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Paula Reyes Aguilera; Maria Teresa Trujillo Rufino; [2023]
    Nyckelord :;

    Sammanfattning : The PLENUM group, formed by researchers and developers of XR methods, aims to develop functions and spaces in virtual reality to improve the design environment. In the field of design reviews, although design reviews are now increasingly being conducted digitally, teams are still reliant on video conferencing software, as currently no dedicated tools are available.

    Nyckelord :;

    Sammanfattning : Altitude test facilities offer a safe and reliable way to perform a wide variety of tests on aircraft engine. Among them, aeroengine transients represent a necessary step in the certification and qualification of engines. LÄS MER

  5. 4. CFD simulation of gas turbine ventilation and gas dilution

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Lokesh Sathyanarayana; [2022]
    Nyckelord :CFD; Gas dilution; Gas turbines; Ventilation;

    Sammanfattning : Gas turbine engines are one of the primary sources of electricity currently in the world. The assembly consists of multiple subsystems all of which are placed within an acoustic enclosure. Dilution ventilation is a widely used and recommended means of protection against the risk of explosion within gas turbine acoustic enclosures. LÄS MER

  7. 5. Development of a CFD Boundary Condition to Simulate a Perforated Surface

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Medet Kiflemariam; [2021]
    Nyckelord :Computational Fluid Dynamics; CFD; Boundary Condition; Bleed; Aerospace Engineering; Aeronautical Engineering; Physics;

    Sammanfattning : In aircraft with jet propulsion engine intakes at supersonic speed, strong pressure waves referred to as shockwaves occur, which may interact with any present boundary layers along the intake surface. The adverse pressure gradients associated with Shock Wave-Boundary Layer Interaction (SWBLI) may cause boundary layer flow separation, which can result in disturbances of the flow that can be harmful to the device or decrease engine performance.
